How do you solve 4x 2y 4?

How do you solve 4x 2y 4?

  1. 4x-2y=4. 4x−2y=4. Subtract 4x from both sides. Subtract 4x from both sides.
  2. -2y=4-4x. −2y=4−4x. Divide both sides by -2. Divide both sides by −2.
  3. y=2x-2. y=2x−2.

How do you do substitution?

The method of substitution involves three steps:

  1. Solve one equation for one of the variables.
  2. Substitute (plug-in) this expression into the other equation and solve.
  3. Resubstitute the value into the original equation to find the corresponding variable.

What is the slope for 4x 2y?

Reorder 5 5 and −2x – 2 x . Using the slope-intercept form, the slope is −2 .

How do you find the slope of y 3x 4?


  1. Any linear equation in the form. y=mx+b. is said to be in slope-intercept form with slope m and y-intercept b.
  2. y=3x+4 is in this form. So the slope is 3 and the y-intercept is 4.
  3. To find the x-intercept, set y=0 and solve for x. 0=3x+4.

How do you solve equivalent equations?

Rules for getting equivalent equation:

  1. Adding (subtracting) same number (or expression) to both sides of the equation will give equivalent equation.
  2. Multiplying (dividing) both sides of the equation by the same non-zero number (or expression) will give equivalent equation.

How do you find equivalent equations?

Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation….For example, these three equations are equivalent to each other:

  1. 3 + 2 = 5.
  2. 4 + 1 = 5.
  3. 5 + 0 = 5.

How do you write an addition equation?

To write a proper addition equation, you have an equals sign. One side shows you the total. The other side shows you what things are being added together. You can have a variable on either side of the equation.
